Re: exists EXPR error

As a side note %new_list{$file} is a syntax error, but the exists error already makes perl die before this can be reported.

> perl
%h{a};
syntax error at - line 1, near "%h{"
Execution of - aborted due to compilation errors.

I don't have a v5.20 I can test on, but I suppose this is either still an error, or at least a warning with the hash slice syntax (the same way `@array[0]` will provoke a warning if they are activated, even in list context, while `@array[0,]` is always valid)	[reply] [d/l] [select]

Hi Eily I'm not sure what you mean, this `%h{a}` is not a hash slice, it has no meaning. (slices always start with an @ :) > @array[0] will provoke a warning ... even in list context, Hmm not sure if I like that. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :)}	[reply] [d/l]
